title: Non-toxic inhibition of extracellular tumor enzymes--potential in cancer therapy.
abstract: Enzymes characteristically found in the extracellular fluid of tumors, or in elevated concentration in the plasma of tumor-bearing hosts--such as certain glycosidases, certain proteases, and tyrosinase--may possibly play a role in maintaining malignant transformation, promoting tumor invasion, or preventing immune rejection. Experimental data suggests that inhibition of these enzymes could have clinical value. A possible role for such inhibition in a generalized "reverse transformation" strategy is proposed.
